deleteSlice(1) deletes the second image of a stack

[JiHO-2]

Hello everyone,

I am probably doing something wrong, otherwise this looks like a bug:

import ij.*;
import ij.process.*;
import ij.gui.*;
import java.awt.*;
import ij.plugin.*;
import ij.plugin.filter.PlugInFilter;

public class Delete_First implements PlugInFilter {

     ImagePlus im;
     ImageStack stack;

     public int setup(String arg, ImagePlus im) {
         this.im = im;
         return DOES_ALL+STACK_REQUIRED;
     }

     public void run(ImageProcessor ip) {

         // Delete first slice of the stack
         stack = im.getStack();
         stack.deleteSlice(1);

         im.updateAndDraw();
     }
}

This deletes the second image of the stack. stack.deleteSlice(0) gives  
an array out of bounds error.

Thanks in advance for your help. Sincerely,

JiHO

Just like in the "Delete Slice" function, you need to

        im.setStack(null, stack);

here.
